I took a side by side picture of my 2012 Tacoma wheel with the plastic chrome cover next to my spare tire without the cover. For those that don't care for the chrome, the silver powdercoat is a nice alternative. I also took a pic of my 2005 Sequioa wheel which happens to be very similar to the Tacoma wheel.

edit: nm, just read the upgrade goes from a 17" to 18" wheel. But still, I don't know how I would feel about chrome covers, especially when spending 30+ for the truck. Not trying to insult you, just questioning Toyota decision making; unless this is common, then I'm bewildered.

edit2: Just found out there is "chrome clad" and "chrome plated"...guess you learn something every day.

Honestly, you can hardly tell they are plastic covers until you clean the wheel. Most all auto manufactures have went this route with factory "chrome" wheels. Perfect for 95% of folks who never modify or take care of their vehicles. Especially up north with all of the rock salt.

Real chrome in PA is a NO-NO! I work as a mechanic and we do change some tires here and there and I see it all the time that a chrome wheel starts to peel after 3 years. These caps look as real as the real thing with almost no negative side downsides, except that you don't have a real chrome wheel

i hate chrome, the plastic covers are, however a great idea. people dont know how to take care of actual chrome wheels and in severe winter areas, salt destroys them. having said that... my xd monsters are on their way
